Telomerase maintains the telomeres of chromosomes in order to prevent cell death. This enzyme added sequences onto the ends of the chromosomes, thereby preventing extreme shortening and loss of genetic material. In a way, telomerase would give cells immortal life, by continuously regenerating its ends. However, telomerase are usually inactive in the human body because normal cells do not divide frequently, and therefore, the chromosomes do not shorten.
What else can I help you with?
What is the enzyme that replicates the end of chromosomes?
Telomerase is the enzyme that replicates the end of chromosomes, specifically the telomeres. Telomeres are protective caps at the ends of chromosomes that shorten with each cell division, and telomerase helps maintain their length to prevent loss of genetic information and cellular senescence.
What is the chemical telomerase used for?
In science, the chemical telomerase is enzyme that is part of the DNA structure in humans. The chemical is used to help hinder the loss of important DNA in the ends of chromosomes.
The enzyme telomerase solves the problem of replication by?
Telomerase helps solve the problem of DNA replication by adding repetitive sequences to the ends of chromosomes, known as telomeres. This prevents the loss of important genetic information during each round of cell division. By preserving the length of telomeres, telomerase maintains the stability and integrity of chromosomes.
What enzyme works to add DNA to ends of chromosomes in rapidly cells such as those found in an embryo to prevent genes from being lost durintg replication?
Telomerase is the enzyme responsible for adding repetitive DNA sequences to the ends of chromosomes, known as telomeres. This helps prevent the loss of genes during DNA replication in rapidly dividing cells, such as those found in embryos. Telomerase maintains the length of telomeres, ensuring chromosomal stability and integrity.
How are telomeres replicated?
Telomeres are replicated by an enzyme called telomerase. Telomerase adds repetitive DNA sequences to the ends of chromosomes, counteracting the shortening that occurs during DNA replication. This process helps maintain the length of telomeres and preserve cell division capacity.
Do humans possess telomerase, the enzyme responsible for maintaining the length of telomeres?
Yes, humans do possess telomerase, the enzyme responsible for maintaining the length of telomeres.
What do telomerase do?
enzyme that helps in sythesis and elongation of telomere length
What is the enzyme that replicates the end of chromosomes?
Telomerase is the enzyme that replicates the end of chromosomes, specifically the telomeres. Telomeres are protective caps at the ends of chromosomes that shorten with each cell division, and telomerase helps maintain their length to prevent loss of genetic information and cellular senescence.
How are cancerous cells different from other cells?
contain high level of telomerase enzyme
What enzyme is present in cancer cells which scientists believe allows the cancer cells to keep growing indefinitely?
The enzyme present in cancer cells that allows them to keep growing indefinitely is called telomerase. Telomerase helps maintain the length of the telomeres, which are the protective caps on the ends of chromosomes. By preventing telomeres from shortening with each cell division, telomerase enables cancer cells to keep dividing and growing uncontrollably.
What is the chemical telomerase used for?
In science, the chemical telomerase is enzyme that is part of the DNA structure in humans. The chemical is used to help hinder the loss of important DNA in the ends of chromosomes.
What enzyme is present in cancer cells which scientists believe allows the cancer cells?
D. Telomerase

Why does cancer grow out of control?
cancer cells it produce an enzyme (telomerase) that make cells dividing uncontrolled.
Enzyme responsible for indefinite growth of human cancer cells?
Telomerase is responsible for indefinite growth of human cancer cells.
Is telomerase a ribozyme?
No, it is an enzyme. Some textbooks claim it to be a ribozyme, but it is definitely an cellular enzyme. It has a reverse transcriptase part and a rna part. it uses the rna part as a primer and elongates the 3' end of a DNA strand which has been shortened during replication. It is usually not expressed in eucryotic cells but is active in proliferating eucaryotic cells such as germ cells. In tumor cells telomerase may be re-activated and thus the cell proliferates unrestrainedly.
Which human chromosome carries the gene for the enzyme telomerase?
Chromosome 5.The gene is known as TERT (or, in humans, hTERT) and is the most distal gene on the short arm of chromosome 5 (5p). Its location is 5p15.33. For more detail, see the link below.
